    Normative data for the Rey-Osterrieth and the Taylor complex figure tests in Quebec : french people
    (Elsevier Science, 2014-12-03) Potvin, Olivier; Tremblay, Marie-Pier; Gagnon, Jean-François; Belleville, Sylvie; Macoir, Joël; Callahan, Brandy; Caza, Nicole; Hudon, Carol; Ferland, Guylaine
    The Rey-Osterrieth (ROCF) and Taylor (TCF) complex figure tests are widely used to assess visuospatial and constructional abilities as well as visual/non-verbal memory. Normative data adjusted to the cultural and linguistic reality of older Quebec-French individuals is still nonexistent for these tests. In this article, we report the results of two studies that aimed to establish normative data for Quebec-French people (aged at least 50 years) for the copy, immediate recall, and delayed recall trials of the ROCF (Study 1) and the TCF (Study 2). For both studies, the impact of age, education, and sex on test performance was examined. Moreover, the impact of copy time on test performance, the impact of copy score on immediate and delayed recall score, and the impact of immediate recall score on delayed recall performance were examined. Based on regression models, equations to calculate Z scores for copy and recall scores are provided for both tests.

    Normative data for the Montreal cognitive assessment in middle-aged and elderly Quebec french people
    (Elsevier Science N, 2016-10-22) Castellano, Christian-Alexandre; Potvin, Olivier; Tremblay, Marie-Pier; Laforest, Sophie; Cunnane, Stephen C.; Monetta, Laura; Tremblay, Pascale; Larouche, Eddy; Boucher, Linda; Bergeron, David; Bélanger-Gagnon, Jean-François; Belleville, Sylvie; Macoir, Joël; Lorrain, Dominique; Laforce, Robert; Hudon, Carol; Gosselin, Nadia
    Objective: Given that aging is associated with higher risk of cognitive decline and dementia, improving early detection of cognitive impairment has become a research and clinical priority. The Montreal Cognitive Assessment (MoCA) is a screening instrument used to assess different aspects of cognition. Despite its widespread use, norms adjusted to the sociodemographics of Quebec-French people are not yet available. Such norms are however important because performance on neuropsychological tests varies according to sociodemographic variables including age, sex, and education. As such, the present study aimed to establish normative data for the MoCA in middle-aged and elderly Quebec-French population. Method: For that purpose, 1,019 community-dwelling older adults aged between 41 and 98 were recruited. Participants from 12 recruiting sites completed the MoCA. Regression-based normative data were produced and cross-validated with a validation sample (n = 200). Results: Regression analyses indicated that older age, lower education level, and male sex were associated with poorer MoCA scores. The best predictive model included age (p < .001), education (p < .001), sex (p < .001), and a quadratic term for education (education X education; p < .001). This model explained a significant amount of variance of the MoCA score (p < .001, R2 = 0.26). A regression equation to calculate Z scores is presented. Conclusions: This study provides normative data for the MoCA test in the middle-aged and elderly French-Quebec people. These data will facilitate more accurate detection and follow-up of the risk of cognitive impairment in this population, taking into account culture, age, education, and sex.

    Le rôle de la mémoire sémantique dans la reconnaissance des émotions
    (2017) Tremblay, Marie-Pier; Macoir, Joël; Hudon, Carol
    La mémoire sémantique sous-tend plusieurs processus cognitifs et des travaux récents suggèrent qu’elle soit impliquée dans la reconnaissance des émotions. Toutefois, le rôle de la mémoire sémantique dans la reconnaissance de la valence émotionnelle et des émotions de base évoquées par différents stimuli demeure controversé. Par conséquent, l’objectif de cette thèse consiste à clarifier le rôle de la mémoire sémantique dans la reconnaissance des émotions. Pour ce faire, la reconnaissance des émotions est examinée auprès de personnes atteintes de la variante sémantique de l’aphasie primaire progressive (vsAPP), une maladie neurodégénérative caractérisée par une détérioration progressive et isolée de la mémoire sémantique. Dans une première étude, la vsAPP est utilisée comme modèle d’altération de la mémoire sémantique. La performance de personnes atteintes de la vsAPP (n = 10) est comparée à celle de participants sans troubles cognitifs (n = 33) dans trois tâches évaluant la reconnaissance 1) des émotions de base évoquées par des visages expressifs, 2) des extraits prosodiques, et 3) de la valence émotionnelle véhiculée par des photographies de scènes visuelles. Les résultats révèlent que les personnes atteintes de la vsAPP ont des difficultés dans la reconnaissance des émotions de base, à l’exception de la joie et de la surprise évoquées par les visages expressifs, et de la valence émotionnelle. Ces résultats suggèrent que la mémoire sémantique joue un rôle central dans la reconnaissance des émotions de base et de la valence émotionnelle, mais que ce rôle diffère selon le stimulus employé et l’émotion véhiculée. Dans une deuxième étude, les liens formels sont étudiés entre la reconnaissance de la valence émotionnelle et des émotions de base, d’une part, et la mémoire sémantique, d’autre part. Les performances des mêmes participants sont comparées dans deux tâches évaluant la reconnaissance de la valence émotionnelle évoquée par des mots et des émotions de base véhiculées par la musique. De plus, la performance des personnes atteintes de la vsAPP est mise en lien avec la reconnaissance des mots et des extraits musicaux, de même qu’avec la capacité à associer les mots et les extraits musicaux à des concepts. Les résultats révèlent que la reconnaissance de la valence émotionnelle évoquée par des mots et des émotions de base véhiculées par des extraits musicaux dépend de la reconnaissance des mots et des extraits musicaux, mais non de la capacité à associer les mots et les extraits à des concepts. Ces résultats suggèrent que l’activation des représentations sémantiques relatives aux mots et aux extraits musicaux ne joue pas un rôle central dans la reconnaissance des émotions. Dans l’ensemble, les résultats de cette thèse suggèrent que la mémoire sémantique occupe un rôle central dans la reconnaissance de la valence émotionnelle et des émotions de base, mais que l’activation des représentations sémantiques relatives aux stimuli émotionnels n’est pas un prérequis à la reconnaissance des émotions. Ces conclusions contribuent à raffiner les théories actuelles sur le traitement des émotions, des mots et de la musique, ainsi que les modèles de la mémoire sémantique.

    Semantic memory impairment for biological and man-made objects in individuals with amnestic mild cognitive impairment or late-life depression
    (Sage Publications, 2014-10-24) Tremblay, Marie-Pier; Joubert, Sven; Rousseau, François; Macoir, Joël; Callahan, Brandy; Belleville, Sylvie; Hudon, Carol; Bouchard, Rémi W.; Verret, Louis
    Objective: Amnestic mild cognitive impairment (aMCI) and late-life depression (LLD) both increase the risk of developing Alzheimer’s disease (AD). Very little is known about the similarities and differences between these syndromes. The present study addresses this issue by examining the nature of semantic memory impairment (more precisely, object-based knowledge) in patients at risk for developing AD. Methods: Participants were 17 elderly with aMCI, 18 with aMCI plus depressive symptoms (aMCI/D+), 15 with LLD and 29 healthy control subjects. All participants were aged 55 years or older and were administered a semantic battery designed to assess semantic knowledge for 16 biological and 16 man-made items. Results: Overall performance of aMCI/D+ participants was significantly worse than the three other groups, and performance for questions assessing knowledge for biological items was poorer than for questions relating to man-made items. Conclusion: This study is the first to show that aMCI/D+ is associated with object-based semantic memory impairment. These results support the view that semantic deficits in aMCI are associated with concomitant depressive symptoms. However, depressive symptoms alone do not account exclusively for semantic impairment, since patients with LLD showed no semantic memory deficit.

    Validation de stimuli prosodiques émotionnels chez les Franco-québécois de 50 à 80 ans
    (Cambridge University Press, 2014-04-25) Tremblay, Marie-Pier; Morneau-Sévigny, Flore; Presseau, Sophie; Pouliot, Joannie; Ratté, Marie-Hélène; Macoir, Joël; Hudon, Carol
    Peu de banques de stimuli prosodiques ont été validées chez les Québécois francophones. La validation de ce type de banques est nécessaire pour développer des tâches auditivo-verbales chez cette population. L’objectif de cette étude est de valider une banque de stimuli prosodiques émotionnels auprès de Franco-québécois vieillissants. La banque de 195 stimuli (Maurage, Joassin, Philippot & Campanella, 2007 ) a été administrée à 50 Québécois sains âgés de 50 à 80 ans. Les pourcentages de bonnes réponses pour chaque stimulus ont été calculés. Pour chaque émotion, des alphas de Cronbach ont été calculés pour évaluer la cohérence interne des stimuli. Quarante des 195 stimuli ont été reconnus correctement par au moins 80 pour cent des participants. L’émotion la mieux reconnue était la colère; le dégoût était la moins bien reconnue. Cette étude fournit des données qui guideront le choix de stimuli prosodiques viables à des fi ns d’évaluation auprès de Franco-québécois.

    The Victoria Stroop Test : normative data in Quebec-French adults and elderly
    (Pergamon, 2016-11-24) Potvin, Olivier; Tremblay, Marie-Pier; Belleville, Sylvie; Domingues, Nélia Sofia; Gaudreau, Geneviève; Gagnon, Lise; Macoir, Joël; Hudon, Carol; Bier, Nathalie; Blanchet, Sophie
    Objective: Despite the widespread use of the Victoria Stroop Test (VST; Regard, 1981) in clinical and research settings, information regarding the impact of sociodemographic variables on test performance in Quebec-French adults and elderly people is still nonexistent. Thus, this study aimed to establish normative data for error scores and completion time on all test trials (Dot, Word, and Interference) taking into account the impact of age, education and sex on test performance. Method: The sample consisted of 646 community-dwelling and healthy Quebec-French individuals aged between 47 and 87 years. Results: Regression analyses indicated that age was associated with completion time and error scores on all trials. The association was also positive for low and high interference conditions. Education was associated with completion time on Word and Interference trials, and with both interference scores. Finally, sex was associated with completion time on all trials, with women being consistently faster than men. Equations to calculate Z scores and percentiles are presented. Conclusions: Norms for the VST will ease interpretation of executive functioning in Quebec-French adults and elderly and favor accurate discrimination between normal and pathological cognitive states.

    Normative data for a computer-assisted version of the auditory three-consonant Brown-Peterson paradigm in the elderly French-Quebec population
    (Swets Pub., 2014-02-05) Potvin, Olivier; Belleville, Sylvie; Tremblay, Marie-Pier; Ferland, Guylaine; Macoir, Joël; Callahan, Brandy; Hudon, Carol
    The Brown-Peterson task is used to assess verbal short-term memory as well as divided attention. In its auditory three-consonant version, trigrams are presented to participants who must recall the items in correct order after variable delays, during which an interference task is performed. The present study aimed to establish normative data for this test in the elderly French-Quebec population based on cross-sectional data from a retrospective, multi-center convenience sample. A total of 595 elderly native French-speakers from the province of Quebec performed the Memoria version of the auditory three-consonant Brown-Peterson test. For both series and item-by-item scoring methods, age, education, and, in most cases, recall after a 0-second interval were found to be significantly associated with recall performance after 10-second, 20-second, and 30-second interference intervals. Based on regression model results, equations to calculate Z scores are presented for the 10-second, 20-second and 30-second intervals and for each scoring method to allow estimation of expected performance based on participants’ individual characteristics. As an important ceiling effect was observed at the 0-second interval, norms for this interference interval are presented in percentiles.

    The role of semantic memory in the recognition of emotional valence conveyed by written words
    (Routledge, 2019-05-15) Tremblay, Marie-Pier; Wilson, Maximiliano Agustin; Macoir, Joël; Laforce, Robert; Hudon, Carol
    The main goal of this study was to examine the role of semantic memory in the recognition of emotional valence conveyed by words. Eight participants presenting with the semantic variant of primary progressive aphasia (svPPA) and 33 healthy control participants were administered three tasks designed to investigate the formal association between the recognition of emotional valence conveyed by words and the lexical and semantic processing of these words. Results revealed that individuals with svPPA showed deficits in the recognition of negative emotional valence conveyed by words. Moreover, results evidenced that their performance in the recognition of emotional valence was better for correctly than for incorrectly retrieved lexical entries of words, while their performance was comparable for words that were correctly or incorrectly associated with semantic concepts. These results suggest that the recognition of emotional valence conveyed by words relies on the retrieval of lexical, but not semantic, representations of words.

    The contribution of semantic memory to the recognition of basic emotions and emotional valence : evidence from the semantic variant of primary progressive aphasia
    (Psychology Press, 2019-02-15) Tremblay, Marie-Pier; Wilson, Maximiliano Agustin; Macoir, Joël; Laforce, Robert; Hudon, Carol
    There is compelling evidence that semantic memory is involved in emotion recognition. However, its contribution to the recognition of emotional valence and basic emotions remains unclear. We compared the performance of 10 participants with the semantic variant of primary progressive aphasia (svPPA), a clinical model of semantic memory impairment, to that of 33 healthy participants using three experimental tasks assessing the recognition of: 1) emotional valence conveyed by photographic scenes, 2) basic emotions conveyed by facial expressions, and 3) basic emotions conveyed by prosody sounds. Individuals with svPPA showed significant deficits in the recognition of emotional valence and basic emotions (except happiness and surprise conveyed by facial expressions). However, the performance of the two groups was comparable when the performance on tests assessing semantic memory was added as a covariate in the analyses. Altogether, these results suggest that semantic memory contributes to the recognition of emotional valence and basic emotions. By examining the recognition of emotional valence and basic emotions in individuals with selective semantic memory loss, our results contribute to the refinement of current theories on the role of semantic memory in emotion recognition.
